Judges 5:7 change wording to make better sense. The original is very uncertain here since it is the only use of the Hebrew word and sounds like other words that could make equally good sense. This choice makes clearer sense within the context.
Judges 2:6 correct wording by adding "Now" before the sentence and "had" as the helping verb. This connotes that this parenthetical reference to Joshua is from a prior period to provide background for the following description of Israel's loss of covenantal obedience.
Judges 2:2 change wording from "You must make no treaty with those who live..." to what you see because the same word (berith) is used. There is a special significance to "berith" or "covenant" with religious connotations. That's why there is the reference in the next sentence to "altars."
